Is the Moon a planet?

Answer

The moon is not a planet.

In 2006, the IAU (the world organization of professional astronomers) established at a general meeting the three criteria for an object of the solar system to be a planet:

– the object must revolve around the sun
– the object must have a quasi-spherical shape (this is only possible if it is heavy enough)
– the object must have cleared the vicinity of its orbit of smaller objects.

However, the moon does not revolve around the sun, but around the earth, and is therefore certainly not a planet.
Eight objects meet the three criteria and are thus cataloged as planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune

Pluto and several other similar objects belong to another class of objects, the dwarf planets. These only meet the first two criteria.

The moon belongs to the class of satellites. They revolve around a planet or dwarf planet.
